unexperienced

So, I'm gonna be 18 in about a month and I'm still a virgin. It's not that I don't want to have sex, I actually do, but I don't know how to let someone know that I actually want to do it. Guys always call me a tease, but that's not always the case. Any advice? I feel weird just telling someone I want to screw😂 but that's the advice I've been getting from my close guy friends and from my best friend.  Help a girl out?
